In the book 'C + + GUI Programming with Qt 4, Second Edition', in the first chapter, in the section explaining and building the "Hello Qt" there is a short paragraph which reads as follows:

"If you are using Windows and Have installed the Qt Open Source Edition and the MinGW compiler, you will have a shortcut to an MS-DOS Prompt window That has all the environment variables set up for Qt Correctly".

On the previous occasion on which you install the QtSDK, I could find the 'MS-DOS Prompt window', the problem is that I can not remember how to do it (not like it to appear, invoke, or where is the shortcut).
.

I need that MS-DOS window because by it I built and ran my Qt applications manually (it was an alternative to using the QtCreator ... using the commands 'qmake-project', 'qmake miApp.pro' , ect.). Please, if anyone can tell me where it is at, I appreciate it highly.

SDK is different from standalone libraries + this book is mightily outdated right now. Anyway, you can use standard cmd in Windows (just click Start and type "cmd"), if you remember to set environment variables first (add <Qt installation dir>/bin to PATH, add <Qt installation dir> to QTDIR).
